IATI Identifier


Within the IATI activity standard, the iati-identifier is the unique reference for an an iati-activity.

The iati-identifier is a concatenation of the reporting-org reference and the reference allocated to iati-activity by the reporting-org. Together, these make the iati-identifier.


When using the IATI activity standard to declare an iati-identifier the following should be considered:

  • The iati-identifier must be unique for every iati-activity within the complete dataset published.

  • The iati-identifier should have no leading or trailing whitespace.

  • It is recommended that no forward slashes (/) or spaces should be contained within the iati-identifier.

  • It is recommended to avoid spaces and non-ascii characters.

  • For example:
    • AA-AAA-123456789-ABC123 is preferable to AA-AAA-123456789-ABC 123.

2.01+ Considerations

In versions 2.01 and above, the following must also be considered:

  • The iati-identifier must begin with either the current IATI organisation identifier for the reporting organisation or a previous identifier reported in the element other-identifier.
